I have been using Tinn-R with R without any problems but when I try to use it with REvolution R I get the following error message when Tinn-R runs the configuration script and gets to the trDDEInstall() function:

## Start DDE
trDDEInstall()
> trDDEInstall()
Error in structure(.External("dotTcl", ..., PACKAGE = "tcltk"), class = "tclObj") :
  [tcl] invalid command name "dde".
In addition: Warning message:
In tclRequire("dde", warn = TRUE) : Tcl package 'dde' not found

I have not found anything about this on the Tinn-R forum and have had no repsonse from the REvolution R forum.
I have checked other R-Help queries but these relate to adding the code for .trPaths which I already have.
Does anyone know how to solve this problem?
